Summary:
We currently cache previews, but the vast majority of previews are never rendered again (e.g., they're a preview of someone partway through typing a comment).
Especially when editing large documents (Legalpad, Phriction), this can bloat the markup cache with data that will never be read and won't get purged for 30 days.
In particular, most of the data on `admin.phacility.com` is currently 1,000 previews of legalpad documents as I made minor edits to them over the course of several hours.
This isn't a big concern, but it's a very easy fix.
Test Plan:
- Previewed a legalpad document, verified that cache rows were not written as I mashed the keyboard.
- Saved the document, verified a new cache row was written.

Summary: Ref T2683. Normally not a big deal, but if a readme has some codeblocks missing the cache can slow things down.
Test Plan:
- Verified we hit the cache.
- Verified TOC still works.

Summary: Ref T3671. Depends on D6674. Continues work in D6673, D6674 and extends it into Legalpad and Phriction. Then deletes a bunch of dead code.
Test Plan: Edited documents in Legalpad and Phriction, verified I got reasonable looking previews.

Summary: I want to use some of these for instructional text in Diffusion. Provide a concrete class to make one-offs cacheable and switch Releeph to use it.
